What Does Multicore Mean?

Multicore refers to an architecture in which a single physical processor incorporates the core logic of more than one processor. A single integrated circuit is used to package or hold these processors. These single integrated circuits are known as a die. Multicore architecture places multiple processor cores and bundles them as a single physical processor. The objective is to create a system that can complete more tasks at the same time, thereby gaining better overall system performance.


This technology is most commonly used in multicore processors, where two or more processor chips or cores run concurrently as a single system. Multicore-based processors are used in mobile devices, desktops, workstations and servers.

Techopedia Explains Multicore

The concept of multicore technology is mainly centered on the possibility of parallel computing, which can significantly boost computer speed and efficiency by including two or more central processing units (CPUs) in a single chip. This reduces the system's heat and power consumption. This means much better performance with less or the same amount of energy.

The architecture of a multicore processor enables communication between all available cores to ensure that the processing tasks are divided and assigned accurately. At the time of task completion, the processed data from each core is delivered back to the motherboard by means of a single shared gateway. This technique significantly enhances performance compared to a single-core processor of similar speed.

Multicore technology is very effective in challenging tasks and applications, such as encoding, 3-D gaming and video editing.
